Github conflict resolution UI should switch to the diff3 conflict style

GitHub has a UI that can be used to resolve merge conflicts from the browser. Currently it uses the default conflict style used by git:

<<<<<<< hexagonrecursion-patch-1
bar
=======
baz
>>>>>>> main

This makes the UI mostly useless as it does not present all the necessary information. Please change it to use the diff3 format instead. See git diff - Should diff3 be default conflictstyle on git? - Stack Overflow
